BACKGROUND 1. Field of the Disclosure

The present disclosure relates generally to an electronic deviceincluding a touch sensor including a fingerprint recognition (orfingerprint verification) in the electronic device and a method ofdriving the touch sensor.

2. Description of the Related Art

As use of electronic devices such as a smart phone, a tablet PC, and awearable device is generalized, a concern about security and theusability of the electronic device increases. In fact, the security andthe usability has a trade-off relationship, and thus it is normal thatthe usability is reduced while the security is increased. However, if atwo-dimensional (2D) fingerprint sensor is installed together with adisplay in an electronic device, a usability of fingerprint recognition,which already provides high security, may be improved innovatively. Auser experience of a normal touch using a touch screen panel (TSP) andthat of a touch for a fingerprint recognition are organically connectedwith each other, and thus the security and the usability may besimultaneously ensured.

As described above, the 2D fingerprint sensor capable of recognizing thefingerprint in the display is an innovative technology, but there aremany technical considerations in implementing the 2D fingerprint sensor.The most prominent are a fingerprint recognition rate and a largecurrent consumption.

The fingerprint sensor installed in the electronic device recognizes ashape of the fingerprint in a swipe method or a touch method, andcompares the recognized fingerprint with previously generatedfingerprint data to authenticate the fingerprint. In order to recognizethe shape of the fingerprint, valleys and ridges of the fingerprintshould be determined. In the determination of the valleys and theridges, various methods are used, and optical, ultrasonic, capacitancemethods, and the like are used.

Among these, the capacitance method is frequently used in an electronicdevice such as a smart phone and a tablet PC. A sensor for a fingerprintrecognition in the capacitance method includes a transmitterelectrode(line) (Tx) and an receiver electrode(line) (Rx). Specially,the Rx is formed in a dense interval for the fingerprint recognition.When a user touches a fingerprint sensor formed of the Tx and Rx, acharge is transmitted from the Tx to the Rx, and a value of thecapacitance received by the Rx is changed according to a distancebetween a finger and the Tx. Since this value is inversely proportionalto a distance, the valleys and the ridges of the fingerprint may begenerated based on this.

The fingerprint sensor using the capacitance may be defined as aone-dimensional (1D) or 2D fingerprint sensor according to a method offorming the Tx and the Rx. The 1D fingerprint sensor is commonlyreferred to as a shape of sweeping a finger, that is a swipe method, andthe 2D fingerprint sensor is referred to as a shape of pushing thefinger, that is a touch method.

The fingerprint sensor may be vertically combined with a touch screen,or may be formed in parallel with the touch screen. Therefore, anoperation and a recognition of the fingerprint sensor may besimultaneously performed while operating a touch screen.

However, in the conventional design of a fingerprint sensor combinedwith a TSP which is an input means of the touch screen, there may be thefollowing problems.

First, a cost increase resulting from an increase to a screen size mayoccur. The fingerprint sensor should accurately scan a shape of thefingerprint of a finger differently from a capacitance type touchscreen. For example, the fingerprint sensor may have Tx and Rx distancesof 50 μm. Tx and Rx distance formations of a considerably dense interval-type are necessary in this process.

A screen of an electronic device such as a smart phone has a tendency tobe large, and thus when a fingerprint sensor corresponding to the sizeof the screen is included in the electronic device, a cost is naturallyincreased according to the size of the screen. However, although thescreen of a tablet PC may be larger than a screen of a smart phone, theTx and Rx distances of the fingerprint sensor should be the same asthose of the smart phone.

Next, a confusion between a touch of the touch screen and a touch of thefingerprint sensor may occur. When the fingerprint sensor is installedin the uppermost side, the lowermost side, the leftmost side, and themost rightmost side of an electronic device screen, a conflict relatedto a user experience (UX) may be generated between a normal touchoperation and a fingerprint recognition operation. For example, when afingerprint input is allowed in an upper side notification panel areaand a button input area of a lower side, the fingerprint recognitionoperation may conflict with the touch operation. In addition, in a caseof a multi-touch operation, a UX between the normal touch operation andthe fingerprint touch operation may become complex.

Accordingly, there is a need to distinguish between a touch input and afingerprint input. Thus, a separate fingerprint input mode may need tobe provided. When a separate fingerprint input mode is provided, apartial fingerprint input may be possible without a need to enable afingerprint input in a whole screen.

Additionally, a difficulty of the fingerprint recognition in a curvedscreen of the electronic device may occur. The fingerprint recognitionis not uniform in the curved screen, and thus the fingerprintrecognition in the touch operation may be difficult.

Finally, a large current consumed in the case of the fingerprintrecognition may occur. In the case of the fingerprint recognition, boththe TSP and the fingerprint sensor must be operated. When thefingerprint sensor is formed of the Tx and the Rx in a whole screen, allTx and Rx should be turned on for a partial recognition since it is notknown where to recognize the fingerprint.

Accordingly, a new structure for a fingerprint sensor installed in aportable electronic device having a TSP, such as a smart phone, a tabletPC, and a wearable device (or wearable apparatus) is needed.

FIG. 3 is a block diagram illustrating a structure in which a touchscreen panel (TSP) and an fingerprint panel (FP) are connected to aprocessor, according to an embodiment of the present disclosure.

Referring to FIG. 3, a TSP 30 may be connected to an ApplicationProcessor (AP) 33 to provide touch information. The touch informationprovides a coordinate such as x and y based on a screen resolution,multi-touch information (e.g., information on the number of inputtouches), information on whether a hovering is generated (e.g.,information on the position and the height of the hovering) and areatouch information (e.g., information on an area of the touch region, andinformation on a long axis and a short axis of an area).

The TSP 30 may be connected to a Supplementary Processor (SP) 32 whichis configured in addition to the AP 33. The SP 32 is a processorindependent from the AP 33. The SP 32 has lower power requirements thanthat of the AP33, but may be driven in comparatively low power comparedto the AP 33. Therefore, the SP 32 may always receive an input from theTSP 30 or the FP 31. Thus, even though the AP 33 is in a sleep state,since the SP 32 is driven in low power, the SP 32 may be alwaysmaintained in an awake state. In addition, even when the AP 33 is in asleep state, that is, a state in which a screen is turned off, it may beconfirmed whether a user input is generated through the TSP 30 and theFP 31.

Each of the panels TSP 30 and FP 31 and each of the processors SP 32 andAP 33 may be connected in various methods such as an Inter-IC (I2C) anda Universal Asynchronous Receiver/Transmitter (UART). If the TSP 30 isconnected to the SP 32, the user may perform the touch input even in thestate in which the AP 33 is the sleep state. For example, when a statein which a screen is touched in a specific condition is sensed, the AP33 may be awakened and thus the screen may be turned on.

In addition, when the FP 31 is connected to the SP 32, the fingerprintrecognition may be performed even in the state in which the AP 33 is inthe sleep state. For example, when a user touches a screen using afinger and thus a specific user is recognized, the screen is awakened,the user is automatically authenticated, and a lock screen may beunlocked. At this time, in the state in which the FP 31 and the TSP 30are connected to the SP 32, and the AP 33 is in the sleep state, onlythe TSP 30 may be executed through the SP 32. If a touch event isgenerated in the TSP 30, a point or an area where the touch event isgenerated may be determined, and the FP 31 matched to a correspondingpoint or area may be enabled.

The FP 31 and the TSP 30 may be directly connected to the AP 33 toreceive the fingerprint recognition or the touch operation.

As described above, the connection among the SP 32, the FP 31 and theTSP 30 may awaken the AP 33 simply from the state in which the AP 33 isthe sleep state or the screen locked state, or may unlock the screen.Therefore, a current consumption is reduced when an electronic device isused, and usability is improved.

A capacitance method has characteristics in which a value is changedaccording to a dielectric constant of a dielectric disposed between theTx and the Rx, and the ridges and the valleys of the fingerprint of thefinger are determined using this characteristics. After this informationis formed in a successive form, an image type is finally formed, andthus a unique pattern of the fingerprint is formed.

The fingerprint sensor may use various methods such as a capacitancetype, an ultrasonic type, and an optical type. However, the basicprinciple is a determination of the ridges and the valleys of thefingerprint of the finger to determine an authentication, and thus thebasic principle is the same.

The fingerprint sensor may include a swipe type (i.e., 1D type) and anarea type (i.e., 2D type) according to a method of implementing the Txand the Rx.

The swipe type recognizes the fingerprint in the Rx which is formed in aline of a 1D type, and forms a shape of the fingerprint by combiningsuccessive images generated at the time of swiping.

In contrast, the area type reads an imprinted type at once and generatesa fingerprint image based on this, when a finger touches an inputsurface in the Tx and the Rx formed in a regular distance.

FIG. 4 is a view illustrating a fingerprint recognition structure of a 2Dimensional (2D) fingerprint sensor, according to an embodiment of thepresent disclosure.

Referring to FIG. 4, a principle of a 2D fingerprint sensor 40 isillustrated. When a finger touches the fingerprint sensor 40, the Rxsenses a change of a capacitance between the Rx and the Tx, and thechange of the capacitance is digitized. A ridge 400 and a valley 410 ofthe fingerprint may be determined through the digitized value, and afingerprint shape may be determined in various steps of gray scalesthrough a total value.

The fingerprint sensor 40 receives a touch input of a user, differentlyfrom a another type of sensor, and thus a layer of a panel type shouldbe formed. This may be referred to as a fingerprint recognition panel ora Fingerprint Panel (FP). For example, the fingerprint recognition panelincludes a fingerprint recognition sensor pattern including a pluralityof first electrodes (i.e., patterns) of a first direction and aplurality of second electrodes (i.e., patterns) of a second direction.

A main object of the FP 40 is the fingerprint recognition, but the FP 40may receive an input through a touch of the touch screen. A basicprinciple of the fingerprint sensor of the capacitance type is notlargely different from that of the TSP, and thus a touch input such as apress, a release and move is possible in addition to the fingerprintinput.

In contrast, since a method of the FP and a method of the TSP aresimilar, when the FP and the TSP are simultaneously executed in anoverlapping state, a value of the Tx becomes large, and a distancebetween the Tx and the Rx becomes not uniform. Therefore, the panelsmutually influence and interfere with each other. Thus, when the TSP andthe FP are simultaneously executed, an accurate measurement of both ofthe TSP and the FP may be difficult. In order to this, an effectivecontrol of the TSP and the FP is important.

FIG. 5 is a view illustrating a complex type touch sensor, according toan embodiment of the present disclosure.

Referring to FIG. 5 a type of sensor in which a TSP 500 and an FP 510are combined is provided. The TSP 500 and the FP 510 form differentlayers, and each of the Tx and Rx patterns overlap. In the case of theTSP 500, when a finger performs a touch input on the TSP 500, acapacitance of an area where the touch input occurs changes. At thistime, a position where the touch input is generated is calculatedthrough positions of the Tx and the Rx of the input area to determinecoordinate information. In the same manner, in the case of the FP 510,when the finger touches the FP 510, a capacitance of the touched areachanges, and the fingerprint image is obtained through a leveling of ameasured value.

As described above, the principles of the TSP 500 and the FP 510 aresimilar. However, a detailed processing method or object may bedifferent. This is because a main function of the TSP 500 is adetermination of a point where a finger touches and a main function ofthe FP 510 is a generation of a shape of the fingerprint in thefingerprint sensor.

The TSP 500 and the FP 510, also have a detailed difference in using adifference of the capacitance. In the case of the TSP 500, when thedistances between the Tx and the Rx are too small, an interference ofthe Tx and the Rx may be generated, and thus it may have a negativeinfluence on determining an accurate position. That is, when a touch istoo sensitive and thus a change of the value is large, a change of ameasured value becomes large and thus a point coordinate is not stablyoutput. Therefore, a touch recognition itself may be felt unnaturally,and thus a certain measured value filtering is necessary. Thus, the TSP500 needs a proper level of Tx and Rx distances (e.g., about severalmm).

In contrast, since the fingerprint sensor of the FP 510 measures shapesof the ridges and the valleys of the fingerprint the distances betweenthe Tx and the Rx should be small. This distance should be a minimumlevel capable of reading a normal pattern of a fingerprint, and shortermay not be better. This distance is not related to the size of theelectronic device. In general, the distance of the Tx and the Rx shouldbe about 50 μm to generate a stable fingerprint image.

Accordingly, in FIG. 5, the TSP 500 and the FP 510 have differentdistances of Tx and Rx. However, the TSP 500 and the FP 510 are notalways arranged in a lattice pattern as shown in FIG. 5. This is merelyan example, and the Tx and the Rx may be disposed in various types.However, there must be a difference in the distances of the Tx and theRx of the TSP 500 and the FP 510, due to characteristics thereof, and amethod for structurally combining these is necessary.

FIGS. 6A to 6C are views illustrating examples in which an FP isdisposed at a TSP according to an embodiment of the present disclosure.

Referring to FIGS. 6A to 6C various examples in which the TSP and the FPare physically disposed are provided. The TSP and the FP may be disposedin various configurations. FIGS. 6A to 6C each illustrate a front view,a plan view and a right side view of the configuration.

Referring to FIG. 6A, is configuration in which the TSP and the FPoverlap. In this configuration, the FP 620 is operated on an area wherethe TSP 610 is driven. This configuration has advantages in which the FP620 may be installed in a random position. But, when the TSP 610 and theFP 620 are simultaneously operated, the Tx is simultaneously operated,and thus a charge amount applied to the Rx is influenced. Therefore, anaccurate measurement may not be performed, and thus an error may begenerated in a recognition of a fingerprint or a touch.

As described above, when the TSP 610 and the FP 620 are simultaneouslydriven, one of the TSP 610 and the FP 620 may be operated, or at leastone Tx may be operated. For example, the fingerprint may be recognizedby stopping a use of the Tx and the Rx of an overlapping area in the TSP610 and using only the Tx and the Rx of the FP 620. Alternatively, a useof the Tx of the TSP 610 may be stopped and only the Tx and the Rx ofthe FP 620 may be used to recognize the fingerprint. This case uses theRx of the TSP 610, and a touch position may be determined using a chargeamount generated between the Tx of the FP 620 and the Rx of the TSP 610.

Referring to FIG. 6B a configuration in which the TSP 630 and the FP 640do not overlap, and are disposed in parallel is provided. The FP 640 isdisposed under the TSP 640. This configuration does not generate aninterference between the TSP 630 and the FP 640. However, when a touchis recognized, the TSP 630 cannot be used as a whole, and a partialsection of a screen must recognize the touch by using the FP 640. Inthis case, when a partial Tx and Rx of the FP 640 are used, the touchoperation may be performed like the TSP 630.

Referring to FIG. 6C a configuration in which the TSP 650 and the FP 660do not overlap, and are disposed in parallel is provided. The FP 660 isdisposed at a right side of the TSP 650. This configuration does notgenerate an interference between the TSP 650 and the FP 660. However,when a touch is recognized, the TSP 630 cannot be used as a whole, and apartial section of a screen must recognize the touch by using the FP660. In this case, when a partial Tx and Rx of the FP 660 are used, thetouch operation may be performed like the TSP 650.

FIG. 7 is a perspective view illustrating an electronic device in whichan FP is disposed at a TSP, according to an embodiment of the presentdisclosure.

Referring to FIG. 7, in an electronic device 70 having a first display710 and a second display 720, since the first display 710 and the seconddisplay 720 basically provide independent user experiences, the FP maybe configured as shown in FIG. 6C. When the second display 720 isconfigured as shown in FIG. 6C, the first display 710 may mainly performa function of a touch, and the second display 720 recognizes afingerprint. Therefore, a panel specialized according to a display maybe provided, and thus a specialized UX may be provided to a user.Although it will be described below, the first display 710 may be a flatdisplay, and the second display 720 may be a curved display.

FIGS. 8A and 8B are views illustrating complex type touch sensors,according to an embodiment of the present disclosure.

Referring to FIGS. 8A and 8B, a TSP and an FP may be implementedsimultaneously in one panel by changing dispositions of a Tx and an Rxand hardware (HW) control structure. The Tx and the Rx forming the TSPand the Tx and the Rx forming the FP are formed in the same panel, andare formed in a hybrid type. Since a single layer (i.e., each panel doesnot overlap and is disposed in parallel) may be used, there is anadvantage in which a thickness of a device may be reduced.

When only the TSP is used, as shown in FIG. 8A, a current is nottransmitted to the Tx and the Rx of the FP, and thus the Tx and the Rxof the FP are not operated. Thus, it may be used in an equivalent manneras a normal TSP.

However, when the TSP and the FP are simultaneously used, as shown inFIG. 8B, the Tx and the Rx of the FP, which are formed at a regulardistance, are added between distances of the Tx and the Rx of the TSP.Therefore, the added area may play a role of a fingerprint sensor. Suchan operation may be controlled in a H/W(hardware) manner according towhether a fingerprint input mode is executed or removed in theelectronic device 70.

FIG. 9 is a view illustrating a swipe operation in a 1D touch sensor,according to an embodiment of the present disclosure.

Referring to FIG. 9, a fingerprint sensor is generally disposed in astructure receiving an input of a flat 2D type. However, in a structurehaving a curved display and a TSP, it may be difficult to apply an FP ina structure of a normal 2D type. This is because when distances of a Txand an Rx are warped, a shape of a fingerprint is twisted. To this solvethis, a line which is perpendicular to a curved direction is set as theRx, and a user may be induced to swipe vertically to a position wherethe Rx is activated. In this case, when the Tx is formed in a uniformdistance, a capacitance is generated between a plurality of arranged Txsand one Rx, and the capacitance is sensed to generate an image. Asdescribed above, when the user swipes a finger, the fingerprint is read,successive images are stored, a fingerprint image is generated, and anauthentication is possible. In order to receive an input through the FPand perform a required operation according to the input, stateinformation of the FP should be defined. The state information meansinformation of the FP matched with an input of the TSP, when a touchinput is received through the TSP. This information is necessary toprovide a proper UI, when an OS or a platform operating the electronicdevice 101 provides a finger related service or function.

The state information of the FP is shown in Table 1.

TABLE 1 State Information Operation state information of the FP:Enable/Disable Input possible area of the fingerprint sensor, which ismatched with a resolution of a display: (x, y, width, height) Example:when it is (10, 10, 200, 400), the display shows that an area where thewidth is 200 and the height is 400 from (10, 10) is the fingerprintsensor input area. Type of the fingerprint sensor: 1D/2D Detailedinformation of the Tx and the Rx Numbers of each Tx and Rx Distanceinformation of each Tx and Rx Information on whether the Tx and the Rxare operated (i.e., activated) or not: Tx[N], Rx[N] Example: when Tx[1]= 1 and Tx[2] = 0, a current is applied to the Tx[1] and the current isnot applied to the Tx[2].

In the state information, the operation state information of the FPcontrols the FP to determine whether the FP is operated when the TSP andthe FP overlap.

The value of the input possible area of the fingerprint sensor, which ismatched with the resolution of the display may be changed according tothe size and the resolution of a real screen of the fingerprint sensorof the electronic device 101. This area should be also matched with atouch coordinate input TSP. Information on this area is provided to theoperating system or the platform in the electronic device 101. Afingerprint related UI may be generated using this area information in amodule forming a GUI.

A type of the fingerprint sensor may be set in a type in which thefingerprint sensor is the 1D method or the 2D method.

The dimension of the sensor may be set by a user, and may be determinedbased on another state information. For example, when the display isflat, the fingerprint sensor of the 2D method may be used, and when thedisplay is curved in one direction, the fingerprint sensor of the 1Dmethod may be used.

A method of inputting by a user should also be changed according to atype (i.e., method) of the fingerprint sensor. Thus, a user guide whichrequires a registration or an input may also be changed based on thetype of the fingerprint sensor.

The detailed information of the Tx and the Rx is information necessaryto control the Tx and the Rx of the fingerprint sensor. When theoperation state information of the FP is disabled, an overall state ofthe Tx and the Rx also be deactivated.

The numbers of each Tx and the Rx indicate the numbers of the Tx lineand the Rx line formed in the fingerprint sensor.

The distance information of each Tx and the Rx indicates distances atwhich the Tx and the Rx are formed, and indicate each number of the Txand the Rx and an area of the fingerprint sensor. This is an elementindicating a comparative position difference when it overlaps with theTSP. The distance information may be indicated as a real distance, andmay also be indicated as a Dot Per Inch (DPI).

The information on whether the Tx and the Rx are operated individuallyactivate the Tx and the Rx, when the fingerprint sensor includes N Txsand M Rxs. Therefore, the Tx and the Rx may be controlled such that onlya partial area may be recognized in a whole of the fingerprint sensor.For example, when Tx[10] to Tx[15] are turned off, a fingerprint sensorof a corresponding area is not operated. Such a setting sets the TRx ofthe FP, which is matched according to a position of the TSP input by theuser, and a position to be activated may be fixed and determinedaccording to characteristics (e.g., a left hand, a right hand, or a userdesignation) of a predetermined user.

In a case of a change between the 1D method and the 2D method of thefingerprint sensor, for a recognition of the 1D method, it may use onlyone Rx by enabling only one Rx to be recognized. Alternatively, the Txand the Rx may be controlled such that the Tx and the Rx may sense indifferent directions by switching the Tx and the Rx. The electronicdevice 101 knows the position where the sensor can recognize thefingerprint in the FP, by using the information on the activated Tx andthe Rx of the sensor, and connects this to the TSP and the display. Whenthis is connected to the TSP, the TSP is activated in an area where theFP is deactivated, and when this is connected to the display, an area ofthe FP may be configured in a UI to be displayed.

FIG. 10 is a flowchart of an operation of driving a fingerprintrecognition of a touch sensor, according to an embodiment of the presentdisclosure.

Referring to FIG. 10, in step 1010, in order to input a fingerprint inelectronic device 101 by a user, a fingerprint sensor should be in aninput mode state.

In step 1020, the fingerprint sensor may always be activated, but it isnormal to turn off the sensor to reduce a current consumption when thesensor is not used in a mobile device.

A reason an activation control of the fingerprint sensor is necessary inthe electronic device 101 is because a problem may be generated when aTSP and an FP in which the fingerprint sensor is installed overlap. Thisis because a charge amount received by the Rx may be changed when thecharge is generated simultaneously in a Tx of the TSP and a Tx of theFP. In the case of the fingerprint sensor, an image is generated using acapacitance generated between the Tx and the Rx. However, when thisvalue is influenced, naturally an image shape is changed, and thus afingerprint authentication cannot be performed.

In step 1030, the FP of the electronic device 101 is activated when auser executes an application or a function for a fingerprint input toinput the fingerprint. At this time, a fingerprint input possible areais defined based on the state information of the FP, and this area isactivated such that the fingerprint input is possible in this area. Inaddition, the application or the function displays a UI which enablesthe user to input the fingerprint.

In step 1040, the user inputs the fingerprint.

When the FP is activated, the TSP of an area where the FP and the TSPoverlap may be operated together. Therefore, as described above, the Txof the TSP influences the Rx of the FP, and thus it may be difficult togenerate an accurate fingerprint shape. Accordingly, when the FP isactivated, at least, the operation of the TSP overlapping the FP iscontrolled. For reference, even when an AP is in a sleep state and thusa display is turned off, the fingerprint recognition is possible.

FIG. 11 is a flowchart of an operation of driving a fingerprintrecognition of a touch sensor, according to an embodiment of the presentdisclosure.

Referring to FIG. 11, a method for operating the fingerprint recognitionusing an FP and a TSP connected to an SP when an AP is in a sleep stateis provided.

In step 1110, the TSP senses a touch of a user.

In step 1120, the FP is activated based on a sensed touch position, oralternatively, only Tx and Rx lines adjacent to a touch area of the TSPmay be activated in the FP.

In step 1130, after a fingerprint input, a fingerprint authentication isexecuted.

In step 1140, a screen is unlocked, or a designated operation such as acamera execution is performed according to the fingerprintauthentication.

FIG. 12 is a view illustrating a complex type touch sensor, according toan embodiment of the present disclosure.

Referring to FIG. 12, an example in which a TSP and an FP aresimultaneously used is provided. In electronic device 101, a processor110 determines whether a fingerprint recognition mode is executed andselectively activates the touch recognition sensor pattern and thefingerprint recognition sensor pattern. When only the TSP is used, Txand Rx lines of the FP are disabled, and thus the TSP may be used.

However, when the TSP and the fingerprint sensor are simultaneouslyused, mutual interference of the TSP and the FP may be controlled not tobe generated, by turning off the Tx line overlapping the FP, among theTx lines of the TSP.

As shown in FIG. 12, the FP is turned on and operated, by turning offn1, n2 and n3 of the Tx line, which are areas overlapping the FP. Inthis case, the TSP knows information on the n1, n2 and n3 in advance.Values of the n1, n2 and n3 may be changed.

FIG. 13 is a view illustrating a touch sensor, according to anembodiment of the present disclosure.

Referring to FIG. 13, when a TSP and an FP do not overlap and aredisposed in parallel, since an interference between the TSP and the FPis not generated, each panel may be used. In this case, in order tomatch a recognition level of the FP with that of the TSP, some of Tx andRx lines may be activated to be used together with Tx and Rx lines ofthe TSP.

The fingerprint sensor senses where a touch is generated and which touchoperation, such as an up, a down, a left and a right, is generated in anavigation mode. However, since a structure and an arrangement of thefingerprint sensor are different from those of the TSP, the fingerprintsensor must calculate a touched position independently from the TSP.Accordingly, in order to drive the TSP and the FP in the manner of onelarge TSP, the TSP and the FP must be synthetically managed to perform aconsistent recognition of a touch position and an operation.

However, to this end, structures of the TSP and the FP must beconsistent and simultaneously processed, and may become complexsystematically. Thus, it may be inefficient and a performance may not begood compared to a case of an operation of a single TSP. Therefore, sucha method may be suitable for an electronic device having a dual displayor first and second displays capable of providing independent UXs andscenarios in each panel.

FIG. 14 is a view illustrating electrode lines of a 2D fingerprintsensor, according to an embodiment of the present disclosure.

As shown in FIG. 14, a touch sensor may be a complex type in which a TSPand an FP are added as a single panel. The complex type touch sensor isa type in which the TSP includes the FP and Tx and Rx lines of the TSPand Tx and Rx lines of the FP overlap. Since the TRx of the FP is denseinterval, in general, denser Tx and Rx are disposed in an arrangement ofthe Tx and the Rx of the TSP.

In the complex type touch sensor, when only TSP is used, the Tx and theRx of the FP may be disabled. However, a common line which performs afingerprint sensor role and is included in the Tx and the Rx of the TSPmust be activated. If the FP is used, the Tx and the Rx of thefingerprint sensor are activated, and the common Tx and Rx lines arealso activated. In addition, a fingerprint sensor area is defined in thecomplex type touch sensor based on a predetermined fingerprint sensorarea, and the Tx and the Rx of a corresponding area are used for thefingerprint recognition. Remaining areas may be used as the TSP.

When the FP is used, the FP may be partially divided and may beactivated, rather than activating all areas in one FR. This may bedesignated by a user setting in a process of a state informationdefinition of the FP. For example, in a case of a right-handed person,the Tx and the Rx of the FP positioned in a right side of a screen maybe activated, and in a case of a left-handed person, the Tx and the Rxof the FP positioned in a left side of the screen may be activated. Thishas an effect of reducing a current consumption by deactivatingunnecessary Tx and Rx.

When the fingerprint is input, an authentication operation is performed.The authentication compares previously registered image information ofthe fingerprint with newly input image information of the fingerprint. Adetermination as to whether the images are matched is performed based ona characteristics point and a pattern of the fingerprint. When a matchscore satisfies a reference condition and thus the authentication ispassed, a fingerprint authentication success is determined.

When the authentication is passed, an operation is performed suitablyfor a scenario previously stored in an executed application or aservice.

FIG. 15 is a view illustrating electrode lines of a 1D fingerprintsensor, according to an embodiment of the present disclosure. FIG. 16 isa view illustrating a switching operation of an input direction of a 1Dfingerprint sensor, according to an embodiment of the presentdisclosure. FIGS. 17A to 17C illustrate a recognition direction for afingerprint recognition on a curved display, according to an embodimentof the present disclosure.

Referring to FIGS. 15 to 17, the fingerprint sensor performs thefingerprint recognition in the 1D or 2D method according to methods ofcontrolling and recognizing Tx and Rx.

The 1D method is a method of reading the fingerprint in a line, and the2D method is a method of reading the fingerprint in an area. Sincefingerprint information is information of two or more dimensions, the 1Dmethod converts the fingerprint into a 2D by moving a finger in a swipeoperation. Thus, the 1D method is also referred to as a swipe type.

The 2D method may be referred to as a touch type or an area type.

Both of the 1D method and the 2D method have advantages and faults, andthus it may not be determined that one method is superior to anothermethod. However, a usability of a touch type is better than that ofanother type. However, in the case of the touch type, there are limitsof a device and a mounting space. In addition, from a point of a view offingerprint registration, a swipe method recognizes a fingerprint atonce. However, in the case of the touch method, several touches may berequired. Each method has advantages and faults according to situations.Therefore, if the fingerprint sensor of the 2D method is used in the 1Dmethod according to a situation, this may have great advantages.

In electronic device 101, the a 1D or 2D mode may be switched byidentifying a use state of a user and a condition. For example, when adisplay is flexible or curved, it may be difficult to authenticate thefingerprint by a touch. This is because a fingerprint input may bedistorted since an input unit is curved. Therefore, in such a case, whena mode is changed to the 1D mode to allow a swipe, an accuratefingerprint may be input.

In addition, the touch method has advantages in the usability, but hasfaults in which a vestige of the fingerprint may remain on a surface ofthe display. Since fingerprint information is extremely personalinformation and thus may cause critical damage when the fingerprintinformation is leaked, the fingerprint information should not be copied.Accordingly, when a method of the fingerprint sensor is changed into theswipe method, the problem of the remaining fingerprint spot may beresolved.

As described above, the fingerprint sensor mode may be changed from the2D mode to the 1D mode, or may be changed from the 1D mode to the 2Dmode, due to a curve of the display in the electronic device 101 and auser setting.

The fingerprint sensor of the 2D mode captures the fingerprint using allTx lines and Rx lines.

In an operation sequence in various embodiments, Rx1 and Rx2 areenabled, Rx1 is set as a Finger Information (FI) and Rx2 is set as aNoise Information (NI), Tx1 to TxN are sequentially turned on, Rx2 andRx3 are enabled, Rx2 is set as the FI, Rx3 is set as the NI, and Tx1 toTxN are sequentially turned on.

Referring to FIG. 15, the 1D mode enables only a pair of FI and NI,among a total of M Rx. In addition, the Tx continuously and sequentiallyturns on and turns off until a finger swipe ends.

For example, Tx1 to TxN are sequentially turned on and turned off, andagain Tx1 to TxN are sequentially turned on and turned off. Acorresponding principle is the same as that of the touch method.

In a case in which the fingerprint sensor of the 1D type recognizing thefingerprint in the swipe method is used, when a direction of a device ischanged, the fingerprint input also should be changed. To this end, inthe case of the fingerprint recognition, a direction of the swipe may bechanged.

In FIG. 16, a switch is added to each of Tx and Rx lines. When a swipeis operated in a vertical direction in the drawing, it may be performedin the existing method. When the swipe is operated in a horizontaldirection, switches for each of the existing Tx and Rx lines are opened.A differential amplifier of the Rx and a switch are closed in the Txline. The Rx line is connected to a Tx source by turning on a switch.Thus, the Tx and the Rx are exchanged. That is, a role of the Tx and arole of the Rx are exchanged using the switch to perform a fingerprintinput.

In FIGS. 17A to 17C, when the fingerprint sensor recognizes a finger ofa person, it is important to generate a shape of the fingerprint withouta distortion. Therefore, it is important to uniformly read a value whenan Rx is contacted with a finger. When a display is curved, an area ofthe finger touching a screen is curved, and thus the shape of thefingerprint may be distorted. This may be an element reducing arecognition rate in the fingerprint sensor of which an accuracy is themost important. Thus, when the display is curved, it should becontrolled such that a hand may touch a straight line area to performthe fingerprint recognition.

In FIGS. 17A and 17B, a flexible display senses a curved direction anddetermines a recognition direction of a fingerprint sensor based on thesensed direction. When a curved axis is identified in a pattern of an Xaxis and a Y axis, a Tx and an Rx may be exchanged through a switchconnecting the Tx and the Rx.

When a display is curved in the X axis, as shown in FIG. 17A, since a 2Dfingerprint recognition cannot be performed, the Rx remains in avertical direction and a swipe may be performed in a direction from leftto right or a direction from right to left to recognize a fingerprint.In the same manner, when the display is curved in the Y axis, as shownin FIG. 17B, the swipe may be performed in a direction from an upperside to a lower side or a direction from the lower side to the upperside. That is, the Rx, which may be distorted when an input panel iscurved, is controlled to be minimized and an accurate image may begenerated by a swipe of a user.

FIG. 18 illustrates a screen of an electronic device in which afingerprint input mode is displayed, according to an embodiment of thepresent disclosure.

Referring to FIG. 18, a fingerprint input GUI disposition is displayedon a screen of the electronic device 101, based on a physical positionof an FP. A fingerprint input module reads predetermined FP areainformation and displays a fingerprint input UI in a position where afingerprint input is possible on a display. When the FP overlaps acentral area of the TSP, a fingerprint input may be induced. Thefingerprint input area is an area where the FP is possible.

When the FP is driven, the TSP of the overlapped area is controlled. Forexample, when the FP is driven, an operation of the TSP of theoverlapped area is turned off, and thus an interference error of afingerprint recognition and a touch recognition is prevented.

The TSP may also be controlled to promptly activate and turn off the FPafter the fingerprint recognition is finished, to enable a user to feelthat a fingerprint input and a touch input are naturally operatedwithout a disconnection.

FIG. 19 illustrates a drag after a touch operation on a screen of anelectronic device, according to an embodiment of the present disclosure.

Referring to FIG. 19, in relation to a drag during a touch and dragoperation, a drag started after a fingerprint recognition is finished inan FP area is linked to a security operation; while a drag in a TSP areawhere the FP and the TSP do not overlap is linked to a differentoperation. For example, in a case of a gallery application, when a dragwithout an FP overlap is performed, a next (or a previous) picture isdisplayed. A drag started after a fingerprint recognition in an FP areamay be linked to the security operation such as turning on and off alock of a corresponding picture.

For another example, in a lock screen, if a swipe is performed in anormal area, it may enter a normal mode, and if the swipe is performedin an area of the FP, it may enter the security mode.

FIG. 20 illustrates a screen of an electronic device in which afingerprint input finger position is sensed and a position of afingerprint input window is changed, according to an embodiment of thepresent disclosure.

Referring to FIG. 20, a fingerprint sensor is designed in a positionwhere a fingerprint recognition is performed in the most comfortableposition when a user's hand grips a device. For example, an FP may bedesigned in a central area to which a finger may be touched aftergripping a device with the hand. A position of a primarily used fingermay be determined based on this. An area where the user often performsthe fingerprint input may be determined, and a fingerprint input windowmay be displayed in a left area, a right area, a central area, or anarea designated by the user. Alternatively, the position of thefingerprint input window may be determined using finger informationhaving a registered finger.

When the hand input by the user is determined as a left hand or a righthand, a UI such as a camera photographing button, a menu configuration,a telephone/message transmission button, a frequently used menu and agame controller may be configured based on this information such that afrequently used hand is comfortable.

When the position of the fingerprint input window is determined, numbersof Tx and Rx lines of an FP corresponding to the GUI form thefingerprint input window. Therefore, in the fingerprint mode, only Txand Rx lines corresponding to the area are activated, and remaining Txand Rx of the FP are deactivated.

FIG. 21 illustrates an operation of a swipe for preventing a fingerprintvestige in a screen of an electronic device, according an embodiment ofthe present disclosure.

Referring to FIG. 21, in a conventional fingerprint recognition of atouch method, a fingerprint is left on a glass of a smart phone surface,and therefore the fingerprint may be copied and used. A method toprevent leaving a fingerprint on the glass is through a swipe.

Accordingly, after a fingerprint authentication, a user may be guided totrace with a finger on a screen of the electronic device 101, a snailshape of which the thickness is gradually thinned; such a gestureenables the user to perform authentication.

After an additional authentication, a pattern for removing thefingerprint is provided to the user as an additional element of asecurity. For example, after the fingerprint authentication isperformed, and a star, a quadrangle, a triangle or a circle isdetermined randomly to be used in a final authentication. Acorresponding pattern recognition is sensed by a TSP touch.

When a flexible display is flat, a touch type fingerprint UI isdisplayed. When the flexible display is curved, a UI may be displayed soas to perform a swipe in a curved direction.

Since a direction perpendicular to a curved direction when the flexibledisplay is curved is an Rx, a Tx and the Rx may be switched according tohorizontal and vertical modes. For example, when the flexible display iscurved in an X axis, it may allow a swipe from an upper side to a lowerside. When the flexible display is curved in a Y axis, it may allow aswipe from left to right. In a case of a touch method, when a touch isweak, the touch may not be recognized at once. Therefore, thefingerprint recognition using the swipe method may be used.

A swipe direction convenient for a user may be different according to adirection in which the electronic device 101 is held. Therefore, theswipe direction may be controlled according to the direction of theelectronic device 101, and this is possible through a switching of theTx and the Rx of the fingerprint sensor.

FIG. 22 illustrates a screen of an electronic device in which afingerprint input position is changed, according to an embodiment of thepresent disclosure.

Referring to FIG. 22, when the electronic device 101 is disposed in avertical direction, a swipe is performed in a direction from an upperside to a lower side of the electronic device 101. In this case, an Rxis in a horizontal direction. In contrast, when the electronic device101 is disposed in a horizontal direction, the swipe is performed in adirection from left to right of the electronic device 101. In this case,the Rx is in the vertical direction when the electronic device 101stands straight. Thus, a UI may be displayed such that the swipedirection may be changed according to the direction of the electronicdevice 101, and thus directions of a Tx and an Rx may be switched.

FIG. 23 illustrates a screen of an electronic device in which afingerprint position is indicated according to an approach of a fingerto the electronic device, according to an embodiment of the presentdisclosure.

Referring to FIG. 23, a user's hand approaches a display of anelectronic device 101 when the display of the electronic device 101 isturned off. The electronic device 101 is operated in low power because aTSP uses an SP. The TSP senses a proximity through a hovering of theuser.

When the electronic device 101 senses a proximity or a touch, theelectronic device 101 displays, in a UI, a position where a fingerprintinput is possible in an area where an FP is positioned. In order todisplay the position on the display, the AP wakes up momentarily.Therefore, the position is shown for a moment and the blinks.Alternatively, the position may be displayed in a low screen brightness,a gray screen, or the like for a minimum current consumption. Inaddition, an FP connected to the SP is activated and a user is easilyable to recognize a fingerprint. When the fingerprint is authenticated,a touch screen may be unlocked.

FIG. 24 illustrates a screen of an electronic device in which a screenunlock is performed using a fingerprint input, according to anembodiment of the present disclosure.

Referring to FIG. 24, when a TSP connected to an SP senses a touch of auser, if the user knows that a touch touches a position where an FP isdisposed, the FP is promptly driven to recognize a fingerprint, and whenthe recognized fingerprint is matched with a designated fingerprint, anunlock screen may be performed.

FIG. 25 is illustrates an electronic device in which a front camerafunction is executed through a shortened input after a fingerprintinput, according to an embodiment of the present disclosure.

Referring to FIG. 25, a fingerprint recognition is finished in an FPdisplayed in a UI of the electronic device 101, and a swipe is performedin a desired direction among up, down, left and right directions.

An unlock function and an app designated by a user in advance aresimultaneously executed according to an angle (e.g., a horizontaldirection and a vertical direction) of the electronic device 101 and aswipe direction. For example, as shown in a fourth drawing of FIG. 25,the unlock function and a selfie camera function (i.e., the frontcamera) is simultaneously executed according to a swipe directionpreviously designated in a vertical state.

FIG. 26 illustrates an electronic device in which a rear camera functionis executed through a shortened input after a fingerprint input,according to an embodiment of the present disclosure.

Referring to FIG. 26, after an FP authentication operation, as describedabove, when a swipe is performed when the electronic device 101 is inpositioned in an upside down state, as shown in a fourth drawing of FIG.26, the rear camera function is executed.

FIG. 27 illustrates an electronic device in which a music playingfunction is executed through a motion input after a fingerprint input,according to an embodiment of the present disclosure.

Referring to FIG. 27, after an FP authentication step, when apredetermined motion operation (e.g., shaking two or three times infront and back directions) is performed, an unlock function and apredetermined music player is simultaneously executed.

FIG. 28 illustrates an electronic device in which an FP is disposed tobe used in a second display of the electronic device, according to anembodiment of the present disclosure;.

The first display 2810 is a flat display and the second display2820 is a curved display. However, the first display 2810 and the seconddisplay 2820 may be formed in either a flat type or a curved type. Thesecond display 2820 may be formed to have a curvature or not to have acurvature. In addition, the first display 2810 or the second display2820 may be formed of a hard or soft display.

In the electronic device 2800, when an FP 2830 is mounted on the seconddisplay 2820 and a swipe is performed in up and down directions torecognize a fingerprint, a lock function, and an unlock function of thefirst display 2810 and second display 2820 may be operated. For example,when the swipe is performed in the up direction, a lock state may beentered, and when the swipe is performed in the down direction, anunlock state may be entered. Even when an AP is asleep, a fingerprintsensor may be connected to an SP to recognize the fingerprint in lowpower and thus a screen may be unlocked.

In an area where the second display 2820 is disposed, the FP 2830 isformed on at least a portion of the second display 2820, and thus acurrent consumption may be minimized.

When the electronic device 2800 is gripped by a hand of a user (in thecase of a right-handed person), the FP 2830 is positioned such that theswipe is performed easily using a thumb. Therefore, usability is notdegraded and only a comfortable position according to the user may beset. A fingerprint verifier portion of the FP 2830 is displayed on thesecond display 2820 to enable the user to know a fingerprint recognitionarea. The fingerprint verifier may be set at different positionsaccording to the user.

FIG. 29 illustrates an electronic device in which a plurality of FPs aredisposed in a second display of the electronic device, according to anembodiment of the present disclosure;.

Referring to FIG. 29, in an area of the second display 2940 of theelectronic device 2900, a plurality of FPs 2910, 2920 and 2930 aredisposed. Therefore, a user performs a fingerprint recognition in themost comfortable area by a user setting. Power is blocked to an FP whichis not used by the user and thus a current consumption may be minimized.

FIG. 30 illustrates an electronic device in which a first displayincludes a TSP and a second display includes an FP, according to anembodiment of the present disclosure.

Referring to FIG. 30, an electronic device 3000 includes a flat firstdisplay 3010 which uses the TSP and the second display 3020 having acurvature which uses the FP. The electronic device 3000 reduces acurrent consumption and minimizes an interference of touch andfingerprint recognitions compared to a case in which the FP is used in awhole display. In addition, a user may be guided such that the user mayintuitively perform an input corresponding to a display through ausability division according to a screen division between the firstdisplay 3010 and the second display 3020.

FIG. 31 illustrates a method of utilizing a fingerprint recognition tocontrol a function of an electronic device, according to an embodiment.

Referring to FIG. 31, when a swipe using a first finger is performed ina second display 3120 of an electronic device 3100 while a fingerprintof a second finger is recognized in an FP disposed in a first display3110 in an AP sleep state, the electronic device 3120 performs anadditional operation such as volume up and down. This gesture enablesthe electronic device 3100 to simply and additionally set and control afunction of the electronic device 3100. This may enable the electronicdevice 3100 to execute a specific application simply, although thedevice does not perform the application after a unlock state. Inaddition, this may prevent a thoughtless setting of another user.

FIG. 32 illustrates a method of utilizing a fingerprint recognitionoperation in a home screen, according to an embodiment of the presentdisclosure.

Referring to FIG. 32, an electronic device 3200 may strengthen a privacyfunction using fingerprint recognition by providing a secret page, whena second swipe of an FP disposed at a second display 3220 is performedimmediately after a first swipe of a TSP disposed at a first display3210 is performed in a direction of the FP, such that the first swipeand the second swipe are performed in succession. This provides a simpleusability by complexly applying a normal unlock scenario and a privateunlock scenario.

FIG. 33 illustrates a screen of an electronic device in which afingerprint recognition is performed through a multi-touch, according toan embodiment of the present disclosure.

Referring to FIG. 33, when two fingers of a user approach an electronicdevice 3300 of which a display 3310 is in an off state and the twofingers are simultaneously put on an FP, the fingerprint of each fingeris read using adjacent Tx and Rx of the FP to receive data.

An equality level between the recognized fingerprint and a fingerprintof a registered user is determined. Although an equality rate of onefinger is insufficient, an equality rate of another finger is calculatedto process a personal authentication, and thus accuracy may be furtherincreased.

In addition, an authentication operation may be performed by putting oneor more fingers on a panel after registering a plurality of fingers whenelectronic device 3310 is in a sleep state.

The finger which is put on the panel is recognized, and an operation(e.g., an operation designated by a business operator or a user)connected to a corresponding finger is performed immediately. Forexample, when the finger which is put on the panel is recognized as anindex finger, a rear camera function may be executed. In addition, whenthe finger which is put on the panel is recognized as a thumb, music maybe played.

FIG. 34 illustrates a method in which a fingerprint recognition isperformed in a wearable device, according to an embodiment of thepresent disclosure.

Referring to FIG. 34, a fingerprint recognition may be performed in awearable device 3410 of a type worn on a wrist.

The wearable device 3410 is worn on a left wrist. All five fingers of aright hand are registered in the wearable device 3410. When a finger ofthe right hand is put on an FP, the finger put on the FP is recognized,and thus an operation designated by a user is performed immediately.When a display is a curved type, a fingerprint recognition is performedby swiping in a curved direction. Since a screen size of the wearabledevice 3410 is smaller than a smart phone, the wearable device 3410 hasa screen size limit. Therefore, a menu depth movement may be difficult.Thus, when a fingerprint is recognized in a screen of the wearabledevice 3410, a desired function is performed as a shortcut function, andthus usability is improved.

When the wearable device 3410 is used, a connected smart phone 3400 or awearable device itself receives a request for the fingerprint input. Inaddition, when the fingerprint input is requested, the wearable device3410 executes a fingerprint input mode.

In the fingerprint input mode, an FP performs a switching operationinstead of a TSP to recognize a fingerprint. In the fingerprint inputmode, the fingerprint of a finger is recognized to recognize the fingerof the fingerprint. After a left hand or a right hand is determinedaccording to the recognized finger and a direction of a UI isdetermined, a screen of the wearable device 3410 or the smart phone 3400may be awakened. When a use of the fingerprint input mode is finished, amode may be entered to a normal mode again, the FP may be deactivated,and the TSP may be operated again.

Each of the above-described elements of the electronic device, accordingto the various embodiments of the present disclosure, may be comprisedof one or more components, and the names of the elements may varyaccording to the kind of the electronic device. The electronic devicemay include at least one of the above-described elements, and some ofthe elements may be omitted or an additional element may be furtherincluded.
